# Known Issues

The following Known Issues have been identified in this release:

Issue # | Known Issue
--- | ---
ISNG-9797 | While in the WebPage Editor, the WebPage Toolbox incorrectly displays the Charts category and its elements, as well as the Data Table element in the Data Display category. The elements in the Charts category, and the Data Table element are currently not supported.
ISNG-9231 | A spreadsheet that exceeds 100 MB cannot be loaded to a job. To avoid this issue, when saving a large spreadsheet that exceeds 75 MB, a Caution message is displayed that prompts to reduce the spreadsheet size by removing any unnecessary tools or cells, or by only including a limited number of LatchImage functions. When creating a new spreadsheet configuration via recipes, the same Caution message is displayed.
ISNG-9209 | When you open a job that was saved with a specific spreadsheet recipe configuration, the "No configuration was loaded" message is displayed next to the Recipe Manager button, even though the configuration was correctly loaded to the job.
ISNG-9101 | When the WriteDiscrete function is configured to control the state of the Pass/Fail LED discrete output that is programmed to flash Red/Green in the Discrete I/O Settings dialog, the Pass/Fail LED indicator on the In-Sight D900 series vision system may incorrectly flash red when it should stay off. For example, if you trigger the vision system after placing the vision system Offline, the Pass/Fail LED indicator should stay off but it flashes red.
ISNG-9031 | If the AcquireImage function’s Trigger Mode is set to Camera, when the vision system is triggered while a job is Online but paused, the discrete output line incorrectly pulses high and the Pass/Fail LED and Error LED indicators on the vision system incorrectly flash. This issue does not occur when the De-Energize Outputs While Paused checkbox is checked in the Discrete I/O Settings dialog.
ISNG-8671 | The ClearResultsBuffer function is not currently supported.
ISNG-8263 | The AcquireImage function in cell A0 cannot be used as a conditional cell in the Cell State dialog. For example, if the Sleep function's cell state is configured as Conditionally Enabled and its Cell Reference is set to A0 in the dialog, the job will be executed immediately after the image acquisition without pausing. Workaround: Use the second argument to specify the condition. For example, if you want to pause the job execution for 5000 milliseconds after the image acquisition, configure the Sleep function as Sleep(5000,A0).
ISNG-7774 | When adding graphics to display in the Web HMI, especially when the graphics are complex (e.g. tracking the outline of a blob pattern), the job will execute slower.
ISNG-7281 | When resetting the In-Sight D900 series vision system to factory defaults, the files saved on the vision system's root directory will not be deleted. Note: Files saved on the vision system's sub-directory (for example, under \images) are deleted.
ISNG-7220, 7228 | If the In-Sight D900 series vision system does not have enough available space (for example, a large number of image files and/or large job file are saved on the vision system), the vision system fails to back up. Workaround: Before backup, save large files to the PC and then delete them from the vision system.
ISHW-1523 | If an acquisition Delay is specified in the AcquireImage property sheet and the vision system receives a trigger, the Exposure Start signal is sent as soon as the trigger is received, and does not wait for the specified Delay to begin acquisition.
ISHW-1523 | The Exposure Complete signal is incorrectly sent when the image acquisition is complete, and not when the exposure is complete.
ISHW-1524 | There is a 0ms - 5ms delay in acquisition time. This affects: Discrete I/O, Assembly I/O for factory protocols, and spreadsheet events programmed to track Trigger, Missed Trigger, Acquisition Start, Exposure Start and Exposure End. The acquisition time reported when the vision system is configured to use Camera Trigger Mode in the AcquireImage property sheet. This can affect the total cycle time reported, if it includes acquisition time.
ISNG-2546 | If you select a cell containing an Event function, and use the Cell State Dialog to set the cell to be disabled, the cell containing the Event function will not be disabled (even though it graphically appears to be disabled). Instead, you will have to disable the cell that is referencing the Event function. For example, if you have a ReadDiscrete function that references an Event function, you would have to disable the ReadDiscrete function instead of disabling the cell containing the Event function.
N/A | Certain notebook power settings and Windows power plan options can affect the operation of the Cognex Security Service and the Cognex Security Dongle, resulting in security violations or other issues while using the adapter. To avoid such issues, configure the power settings of Windows and your PC as described below: Prevent Windows from turning off the USB hub that the Cognex Security Dongle is plugged into. See the Disable Turning Off the USB Hub topic for more information. Prevent Windows from turning off the network adapter(s) of the PC. See the Disable Turning Off the Network Adapter topic for more information. Disable the selective suspension of USB devices in Windows. See the Disable Selective Suspension of USB Devices topic for more information.
